Next, an example of a control method by the lighting system A1 will be described below. 6 and 7 are sequence diagrams showing an operation example of the lighting system A1.

First, as shown in FIG. 6, a request signal is transmitted from the portable terminal Md to an arbitrary sensor device Es (sensor device Esn in the illustrated example) to acquire measurement data (step S1). Specifically, when the user operates the display unit 31 of the mobile terminal Md, the control unit 32 generates a command for instructing acquisition of measurement data to the sensor device Es. The control unit 32 transmits the command as a request signal from the wireless communication unit 35 to the control device Ct via Wi-Fi.

The control device Ct receives the request signal from the mobile terminal Md by the wireless communication unit 24 . The control unit 22 generates request data including the device ID, time information, etc. included in the command. This request data is transmitted from the wireless communication unit 24 via the communication network Cn1, which is a mesh network, to, for example, the lighting fixture L1 closest to the control device Ct among the plurality of lighting fixtures L (step S2).

In the lighting fixture L1 that has received the request data, the control unit 12 confirms that the operation request target of the received request data is not its own device. Then, the request data is transferred from the first wireless communication unit 141 of the wireless communication module 14 to the next lighting fixture L such as another adjacent lighting fixture L (step S3). Also, the lighting fixture L1 converts the request data into the second protocol and transmits it to the sensor device Es1 via the communication network Cn2. The sensor device Es1 does not perform an operation such as measurement when the device ID specifying the operation target included in the request signal does not match the device ID of its own device.

Request data is sequentially transferred among the plurality of lighting fixtures L in the communication network Cn1, and received by the wireless communication module 14 of the lighting fixture Ln. The control unit 12 of the lighting fixture Ln converts the received request data into request data conforming to the second protocol, and transmits the request data from the second wireless communication unit 142 of the wireless communication module 14 to the sensor device Esn via the communication network Cn2. (Step S4).

When the sensor device Esn that has received the request data from the lighting device Ln via the communication network Cn2 recognizes that the device ID specifying the operation target included in the request data is its own device ID, it responds to the supplied data. process. For example, if the sensor unit 41 of the sensor device Esn is a temperature sensor, the temperature of the environment in which the sensor device Esn is installed is measured (step S5). Next, the control unit 42 of the sensor device Esn obtains, for example, the device ID of the sensor device Esn, the position information of the sensor device Esn, the type of the sensor device Esn, the unit of measurement data, the measurement value acquired from the sensor unit 41, the measurement time ( Measurement data Dm including time stamps) is generated and transmitted from the wireless communication unit 44 via the communication network Cn2 (step S6).

In the communication network Cn1, for example the luminaire Ln closest to the sensor device Esn receives the measurement data Dm via the communication network Cn2. The wireless communication module 14 of the lighting device Ln detects the second protocol from the protocol flag in the measurement data Dm, and receives the measurement data Dm by performing processing according to the protocol. Then, the transfer data Dt is generated by converting the measurement data Dm into a data format for communication using the first protocol, and transferred to the adjacent lighting fixture L via the communication network Cn1 (step S7).

In the communication network Cn1, which is a mesh network, the transfer data Dt sequentially transferred between the lighting fixtures L is received by the wireless communication module 14 of the lighting fixture L1. The lighting fixture L1 transmits the transfer data Dt to the control device Ct (step S8).

Upon receiving the transfer data Dt, the control device Ct obtains the device ID of the sensor device Esn, the position information of the sensor device Esn, the type of the sensor device Esn, the unit of measurement data, the measurement acquired from the sensor unit 41, and the location information of the sensor device Esn included in the transfer data Dt. The value, measurement time (time stamp), etc. are converted into a radio signal and transmitted to the portable terminal Md via the communication network Cn3 (step S9).

In the mobile terminal Md, the wireless communication section 35 receives the wireless signal transmitted from the control device Ct. Based on the information contained in the wireless signal received by the wireless communication unit 35, the control unit 32 displays, for example, the device ID of the sensor device Esn, the position information of the sensor device Esn, the type of the sensor device Esn, and the measurement data on the display unit 31. The unit, the measured value obtained from the sensor unit 41, the measurement time (time stamp), etc. are displayed. Note that these displays may be processed and displayed in a form that is easy for the user of the mobile terminal Md to understand, or may be displayed by intentionally omitting any of the information. In addition, as the display format, character display, icon display, display in which these are combined, or the like can be appropriately adopted.

Note that each sensor device Es is not limited to performing measurements in response to a request from the control device Ct, and may perform measurements periodically at predetermined time intervals, for example. The measurement data Dm acquired by this measurement may be transmitted through the processes of steps S6 to S10 described above.

Next, operation of the illumination system A1 will be described.

According to this embodiment, the sensor device Es wirelessly communicates with the lighting fixture L2 via the communication network Cn2, and is a separate device from the lighting fixture L. Therefore, it is possible to relax the restriction on the installation position of the sensor device Es due to the installation position of the lighting device L, and it is possible to install the sensor device Es at a position more suitable for the measurement of the sensor device Es. Therefore, it can be measured by the sensor equipment Es more appropriately.

First, the sensor device Es2 acquires a measured value such as temperature by the sensor unit 41 . The control unit 42 generates measurement data Dm2 including the acquired measurement values, and transmits the measurement data Dm2 from the wireless communication unit 44 to the lighting fixture L2 via the communication network Cn2 (step S11).

The electronic device Eq is an electronic device whose operation can be controlled by an operation control signal from the control device Ct. A specific configuration of the electronic equipment Eq is not limited at all. Examples of the electronic equipment Eq include air conditioners, various types of housing equipment, and various types of production equipment. Air conditioners include fans, circulators, heaters, and air conditioners.

FIG. 12 is a block diagram showing electronic equipment Eq. The electronic equipment Eq of the present embodiment includes a functional unit 51 , a control unit 52 , a storage unit 53 , a wireless communication unit 54 and a power supply unit 55 .

The functional part 51 is a part for performing the main functions of the electronic equipment Eq. For example, if electronic equipment Eq is an electric fan or a circulator, functional unit 51 includes a motor for rotating the fan. Further, when the electronic device Eq is a heater, the functional unit 51 includes a heater. When the electronic device Eq is an air conditioner, the functional unit 51 includes various drive units for the indoor unit and the outdoor unit.

The wireless communication unit 54 has, for example, the same configuration as the wireless communication unit 44 of the sensor device Es.

In this embodiment, the electronic device Eq has a unique device ID like the sensor device Es. A specific example of the device ID is not limited at all, and for example, a MAC (Media Access Control) address is used.

The power supply unit 55 is for supplying electric power necessary for operation to the function unit 51, the control unit 52, the wireless communication unit 54, and the like. The power supply unit 55 is, for example, one having a function as an AC/DC converter for converting commercial 100V or 200V AC power into DC power, a transformation function, or the like, or a rechargeable battery.

As shown in FIG. 11, in lighting system A4, lighting fixture L2, sensor device Es2, and electronic device Eq2 construct one communication network Cn2. Also, the lighting equipment Ln, the sensor equipment Esn and the electronic equipment Eqn construct another communication network Cn2.

An operation example of the lighting system A4 will be described. For example, through steps S1 to S5 shown in FIG. 6, the sensor device Es2 and the sensor device Esn acquire measured values. Next, as shown in FIG. 13, the sensor device Esn generates measurement data Dmn and transmits it to the lighting fixture Ln via the communication network Cn2 (step S21). Further, the sensor device Esn generates measurement data Dmn and transmits it to the lighting fixture Ln via the communication network Cn2 (step S22). The lighting fixture Ln converts the measurement data Dmn into transfer data Dtn, and transfers the transfer data Dtn to the lighting fixture L1 via the communication network Cn1 (step S23). The lighting fixture L2 converts the measurement data Dm2 into transfer data Dt2, and transfers the transfer data Dt2 to the lighting fixture L1 via the communication network Cn1 (step S24).

Upon receiving the transfer data Dt2 and the transfer data Dtn (step S25), the lighting fixture L1 collectively transfers the transfer data Dt2 and the transfer data Dtn to the control device Ct (step S26). The control device Ct analyzes the received transfer data Dt2 and transfer data Dtn (step S27).

In step S27, the control device Ct analyzes the transfer data Dt2 and the transfer data Dtn to determine whether a state change is necessary for each electronic device Eq. The state change of the electronic device Eq mainly means changing the operation of the functional unit 51. When the electronic device Eq is an electric fan, turning ON/OFF the rotation of the fan or changing the rotation speed (air volume) be. In this embodiment, as shown in FIG. 11, the temperature, humidity, etc., which are the measured values included in the transfer data Dt2 and the transfer data Dtn, and, if necessary, the storage unit 23 of the control device Ct. By comparing a predetermined table or the like, a WBGT (Wet Bulb Globe Temperature) value is calculated for each location where the sensor device Es is installed. The control device Ct has reference data that serves as a control reference for each electronic device Eq. ) to determine whether to control the electronic device. In the illustrated example, the WBGT value calculated from the measurement data Dm2 (transfer data Dt2) transmitted from the sensor device Es2 is 25, which is smaller than the reference data of 27 and does not require the state change of the electronic device Eq2. and maintains the electronic equipment Eq2 in a stopped state, for example. On the other hand, the WBGT value calculated from the measurement data Dmn (transfer data Dtn) transmitted from the sensor device Esn is 30, which is larger than the reference data of 27 and is a magnitude that requires the state change of the electronic device Eqn. For example, the state of the electronic device Eqn is changed from the OFF state to the ON state to start air blowing.

As shown in FIG. 14, the control device sends a request signal to change the state of the electronic equipment Eqn, which is a command for air blowing control, to the electronic equipment Eqn at the location where control is required from the WBGT value calculated in step S27. create. Control data is created by combining this command with the device ID of the electronic device Eqn to be instructed. Then, the control data is converted into a radio signal, and the control data is transferred to the lighting fixture L1 near the control device Ct via the communication network Cn1 (step S28).

The control data received by the lighting fixture L1 is sequentially transferred from the lighting fixture L1 to the plurality of lighting fixtures L on the communication network Cn1 (step S29). Having received the control data, the lighting fixture L2 converts the control data into the format of the second protocol and transfers it to the electronic device Eq2 via the communication network Cn2 (step S30). When the device ID indicating the device to be controlled included in the control data does not match the ID of the device itself, the electronic device Eq2 that has received the control data does not change the state and maintains the current state (step S31).

The lighting fixture L2 transfers the control data from the lighting fixture L1 via the communication network Cn1 (step S32), and when the lighting fixture Ln receives the control data, the lighting fixture Ln converts the control data into the format of the second protocol, It is transferred to the electronic equipment Eqn via the communication network Cn2 (step S33). When the device ID indicating the device to be controlled included in the control data matches the ID of the own device, the electronic device Eqn that has received the control data performs the function according to the instruction content for instructing the state change included in the control data. The state of the unit 51 is changed (step S34). In this example, the electronic device Eqn, which is, for example, an electric fan, starts blowing air. This controls the air conditioning at the location n where the electronic device Eqn is installed.

Further, the control device Ct converts the command for displaying the location of the electronic device Eqn that needs to be controlled into a wireless signal, for example, into a WiFi signal, and transmits the wireless signal to the portable terminal Md (step S35). The portable terminal Md that has received the radio signal changes its state by control, for example, as shown in FIG. 15, and displays the location n where the air blowing is started in a visually recognizable manner (step S36). In the illustrated example, the WBGT values at each location are displayed numerically. In this embodiment, the second protocol is used as the protocol for wireless communication between the lighting device L and the electronic device Eq, but a third protocol different from the first protocol and the second protocol may be used. In this case, since the lighting device L needs to be able to transmit and receive three protocols, the wireless communication module 14 becomes complicated, but there is an advantage that the options for the electronic devices Eq that make up the communication network are expanded.

Also according to this embodiment, it is possible to more appropriately measure with the sensor device Es. In addition, since the sensor device Es and the electronic device Eq are included in the same communication network Cn2, the operation of the electronic device Eq installed in a close position can be more appropriately controlled by the control device Ct according to the measurement result of the sensor device Es. can be controlled.
